The deaerator is a mechanical device that is used to separate air from oil. The deaerator is a component of the Integrated Drive Generator (IDG). The Integrated Drive Generator is used in aircrafts as the main power generator. Oil is used in the IDG as a lubricant and coolant. Air is trapped in the oil due to high suction forces of the oil pumps. The entrained air adversely affects the lubricative and thermal properties of oil. Centrifugal forces inside the deaerator are used to remove this entrained air from the oil. Hamilton Sundstrand has several different deaerator models, but has been unable to evaluate the efficiency of oil separation for different designs. Our goal is to evaluate the efficiency of two deaerator models. The evaluation will be based on experimental and theoretical data. The experimental data will be collected using an actual deaerator setup. The theoretical data will be collected using computational fluid dynamic (CFD) software models. ANSYS CFX software will be used for CFD models. The experimental results will then be compared to the theoretical results. An analysis of both results will lead to a better understanding of flow separation.
